Answer: 10 electrons
Explanation:
N represents Nitrogen. Nitrogen has an atomic number of 7, this means in ground state it has 7 electrons also.
But N-3, means Nitrogen has gained 3 more electrons. So, we have 10 electrons
A dynamometer is used in measuring force!
Answer:
Uhhhh I think this is it
Explanation:
Some changes to total pressure, like adding an inert gas that is not part of the equilibrium, will change the total pressure but not the partial pressures of the gases in the equilibrium constant expression. Thus, addition of a gas not involved in the equilibrium will not perturb the equilibrium.
Answer:
The answer will result in one significant digit.
Explanation:
1. Subtract:
12.1 - 12.004 = 0.096
2. ROund to the correct number of significant digits:
For addition and subtraction we round the sum or the difference to the least number of digits after the decimal point there are in the problem.
For example, SInce 12.1 has one number after the decimal point and 12.004 has three numbers after the decimal point, we round the answer to one number after the decimal point because 12.1 is the number in the problem which has the least amount of digits after the decimal point.
We round 0.096 to 0.1.
0.1 has one significant digit.
